The 92-year old monarch doesn’t have an Instagram account and has never made any Instagram post. But that changed on Thursday, March 7, 2019 when she took to Instagram.

Using iPad for her introductory post, the Quuen shared a letter from the Royal Archives that was sent by mathematician and computer pioneer Charles Babbage to Queen Victoria’s husband and Queen Elizabeth’s great-great-grandfather, Prince Albert.

The Queen wrote in her post on the official @TheRoyalFamily account:

“Today, as I visit the Science Museum I was interested to discover a letter from the Royal Archives, written in 1843 to my great-great-grandfather Prince Albert.”

In the letter, Babbage told Queen Victoria and Prince Albert about his invention, the “Analytical Engine”.

Queen Elizabeth added:

“Today, I had the pleasure of learning about children’s computer coding initiatives and it seems fitting to me that I publish this Instagram post, at the Science Museum which has long championed technology, innovation and inspired the next generation of inventors.”

She signed the post “Elizabeth R.”

The Queen’s very first tweet ever was also sent during a visit to the Science Museum, back in 2014. She included the signature “Elizabeth R.” in the tweet as well.
